【摘要】 阿斯喀尔特原生绿柱石（Ｂｅ）矿床是─产于蚀变花岗岩体顶部、属高温气成热液成因的伟晶岩型稀有金属矿床，它主要由中、粗粒似文象伟晶岩带、鲤云母－萤石结构带、条带状钠长石－石英－白云母结构带、石英－白云母－绿柱石结构带，石英核共５个内部结构带组成。它既是岩浆期后高温气成热液成因伟晶岩型稀有金属矿床的一个典型实例，又是花岗岩浆结晶分异，即由片麻状黑云母花岗岩→二云母花岗岩→白云母花岗岩→伟晶岩→石英脉整个演化过程的完整体现。更多还原

【Abstract】 The Ascalt beryllium deposit in the dome of the altered granite consists of the medi um- and coarse-grained graphic Pegmatite zone, pegmatite zone of greisenization, lepidolitequartz texture zone, albite-quartz-muscovite texture zone, quartz-muscovite-beryl texture zone,and massive quartz core. It is a typical rare-metal pegmatite deposit of pneumatolytic-hydrothermal origin, and is a reflection of crystallization differentiation of granitic magma which is from gneissic biotite granite to two-mica granite→muscovite granite→pegmatite→quartz vein.更多还原
